Abstract: In a network area of a wireless network managed by a wireless master device, a wireless slave device performs wireless network communication with another wireless slave device connected by wire to a terminal, and wired network communication with a terminal connected by wire to the wireless slave device.

Abstract: A communication control apparatus for controlling communication by repeatedly sending a control signal to other apparatuses at a given time interval, the communication using a protocol that regulates transmissions of an acknowledgement as a receipt for one or more communication packets, and the control signal allocating, within the given time interval, two types of communication periods which are (i) a one-way communication period in which a one-way communication is performed and (ii) a two-way communication period in which a two-way communication is performed. The communication control apparatus determines, based on an occurrence ratio of the transmissions of the acknowledgement, a length of the one-way communication period, and sends the control signal that allocates a plurality of the one-way communication periods each of which has the determined length.
